Dr. Thomas P. Trezona is originally from Portland and received his undergraduate degree from Portland State University in biology. He then attended graduate school at Portland State University in microbial genetics. His medical training was received at the Oregon Health Sciences University. He then did a General Surgery residency at Harbor-UCLA Medical Center in Southern California. He received his Surgical Oncology and Medical Oncology training at the Stehlin Oncology Clinic and Stehlin Foundation for Cancer Research in Houston, Texas, where he trained with one on the great pioneers in melanoma research and treatment.

He remained at the Stehlin Oncology Clinic for two additional years and in 1994 was awarded the Houston’s Consumer Choice Award for Health Care Providers as the Physician of the Year. Most recently he was recognized as one of Lane County’s Best Doctors in a survey done by Eugene Magazine.

Dr. Trezona moved to Eugene and opened Cascade Surgical Oncology in 1995. He is board certified and an active member in the American College of Surgeons, the American Society for Clinical Oncology, and other national and international Surgical and Oncology Societies. He has published extensively in the oncology literature. Dr. Trezona is the only Surgical Oncologist between Portland and San Francisco with a focus of comprehensive cancer care. He cares for both the surgical and medical oncology needs of his patients in a personal and compassionate way. This specialized focus draws patients from beyond the Eugene/Springfield area. He sees patients from throughout the Willamette Valley, central and southern Oregon and northern California.

There has been a dramatic increase in recent years in the number of melanoma cases that occur in this country, and especially Oregon. Because of this, Dr Trezona has felt the need to develop a clinic focused entirely on the care of people with melanoma. This has led to opening the Oregon Melanoma Center where he will focus his attention only on the care of people with melanoma.

He is married and the father of 2 daughters. Dr. Trezona relaxes with woodworking, boating, and maintaining a coral reef aquarium.

Jaime Steenkolk, LPN

I have worked in medical offices for 30 years and have held leadership roles for 28 of those years. I feel that the profession chose me and I have grown and thrived in the changes that the profession has undergone over the years. I love learning and a few years ago returned to school and obtained my nursing license. I am thankful to work at Oregon Melanoma Center because I not only get to lead an amazing team of professionals; I also get to use my nursing skills providing direct patient care. It is the best of both worlds.

With the many changes in health care over the years the constant that motivates me is the heart of the doctor and staff in realizing that there is more to medicine than treating disease. At Oregon Melanoma Center there is a commitment to being present with the whole person, mind, body and spirit. That’s why I love working here; it challenges me both professionally and personally.
